Damper test system compatible with different loading powers bidirectionally

Abstract

The invention belongs to the technical field of damper testing, and particularly discloses a damper testing system compatible with different loading powers bidirectionally. The system comprises a high-strength steel frame structure, a prestress locking device, an actuator module, a movable bolt module, a pump station module, an energy accumulator module and a controller module, the prestress locking device penetrates through the high-strength steel frame structure in the longitudinal direction, and the actuator module is arranged in the longitudinal direction of the high-strength steel frame structure; the movable bolt module comprises a movable cross beam and rear connecting seats which are arranged at the two ends of the movable cross beam and correspond to the two front connecting seats, the pump station module is connected with the large actuator and the small actuator through hydraulic oil pipes, and the energy accumulator module is connected with the large actuator and the small actuator through hydraulic oil pipes. Through organic combination of the modules, a high-performance dynamic test system is formed and has two functions of large load, high speed, large displacement, long period, low load, high frequency and small displacement.

Description

technical field [0001] The invention belongs to the technical field of damper testing, and more particularly relates to a damper testing system bidirectionally compatible with different loading powers. Background technique [0002] The damper is a device that uses damping to reduce energy consumption. It is used in the field of vibration reduction and isolation of bridges and buildings. The quality of the damper plays a vital role in the construction of a project. Therefore, the damper is , a series of type tests are required to check the various performance indicators of the damper. With the rapid development of bridges and buildings in our country, the demand for research and development of large-size, long-stroke, high-speed, high-frequency damper products has increased suddenly, but some existing test devices in China can only perform low-speed short-displacement or low-speed The frequency band displacement test, and the domestic damper type inspection require 50,000 sm...

With the rapid development of bridges and buildings in our country, the demand for research and development of large-size, long-stroke, high-speed, high-frequency damper products has increased suddenly, but some existing test devices in China can only perform low-speed short-displacement or low-speed The frequency band displacement test, and the domestic damper type inspection require 50,000 times of small displacement and high frequency fatigue tests. The traditional structure of the damper testing machine cannot meet the test needs of the current structural engineering damper.
